Magento: change applied attribute product types

3rd April 20183rd April 2018 SheldonNo Comments

Sometimes it is necessary to change the product type(s) an attribute is applied to in Magento. A common example is, that you designed and implemented an attribute for a configurable product, because you thought its real world value is equal over all child manifestations. But after a while you realize, that there are differences that you […]

Magento change attribute scope in setup script

21st September 2017 SheldonNo Comments

This code snippet shows how to change attribute scope in a setup script:

<?php
/* @var $oInstaller Mage_Catalog_Model_Resource_Setup */
$oInstaller = $this;

$oInstaller->startSetup();

$oInstaller->updateAttribute(
    'catalog_product', 'abc_attribute', 'is_global',
    Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE
);
$oInstaller->updateAttribute(
    'catalog_product', 'xyz_attribute', 'is_global',
    Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE
);

$oInstaller->endSetup();

// mark index as "reindex required"
$aIndexerCodes = [
    'catalog_product_attribute',
    'catalog_product_flat',
    'catalogsearch_fulltext'
];

$oIndexer = Mage::getModel('index/process');
foreach ($aIndexerCodes as $sCode) {
    $oIndexer->load($sCode, 'indexer_code')
        ->changeStatus(Mage_Index_Model_Process::STATUS_REQUIRE_REINDEX);
}

//clear EAV Cache:
$oInstaller->cleanCache();

<?php

/* @var $oInstaller Mage_Catalog_Model_Resource_Setup */

$oInstaller = $this;

$oInstaller->startSetup();

$oInstaller->updateAttribute(

'catalog_product', 'abc_attribute', 'is_global',

Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE

);

$oInstaller->updateAttribute(

'catalog_product', 'xyz_attribute', 'is_global',

Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE

);

$oInstaller->endSetup();

// mark index as "reindex required"

$aIndexerCodes = [

'catalog_product_attribute',

'catalog_product_flat',

'catalogsearch_fulltext'

];

$oIndexer = Mage::getModel('index/process');

foreach ($aIndexerCodes as $sCode) {

$oIndexer->load($sCode, 'indexer_code')

->changeStatus(Mage_Index_Model_Process::STATUS_REQUIRE_REINDEX);

}

//clear EAV Cache:

$oInstaller->cleanCache();

Associate products to all websites more performant

6th September 2016 SheldonNo Comments

Recently I had to associate all products of a shop to newly created websites in a setup shell script (Associate products to all websites). This could have been implemented like that:

<?php
/**
* Associates products to the newly created websites
*/
private function _associateProducts()
{
    $aWebsiteIDs = Mage::getModel('core/website')
                   ->getResourceCollection()
                   ->getAllIds();

    //remove default website
    array_shift($aWebsiteIDs);

    // bad way would have been:
        foreach (Mage::getModel('catalog/product')->getCollection() as 
                 $oProduct){
            $oProduct->setWebsiteIds($aWebsiteIDs)->save();
        }
        
}

<?php

/**

* Associates products to the newly created websites

private function _associateProducts()

{

$aWebsiteIDs = Mage::getModel('core/website')

->getResourceCollection()

->getAllIds();

//remove default website

array_shift($aWebsiteIDs);

// bad way would have been:

foreach (Mage::getModel('catalog/product')->getCollection() as

$oProduct){

$oProduct->setWebsiteIds($aWebsiteIDs)->save();

}

A much better approach was it to use class Mage_Catalog_Model_Product_Action like that:

<?php
/**
* Associates products to the newly created websites
*/
private function _associateProducts()
{
    $aWebsiteIDs = Mage::getModel('core/website')
                   ->getResourceCollection()
                   ->getAllIds();

    //remove default website
    array_shift($aWebsiteIDs);

    //getAllIds();
    $aProductIds = Mage::getModel('catalog/product')
                   ->getResourceCollection()
                   ->getAllIds();

    // good way (better performance) @see Mage_Catalog_Model_Product_Action
    $oProductActionModdel = Mage::getSingleton('catalog/product_action');
    $oProductActionModdel->updateWebsites(
        $aProductIds,
        $aWebsiteIDs,
        'add'
    );
}

<?php

/**

* Associates products to the newly created websites

private function _associateProducts()

{

$aWebsiteIDs = Mage::getModel('core/website')

->getResourceCollection()

->getAllIds();

//remove default website

array_shift($aWebsiteIDs);

//getAllIds();

$aProductIds = Mage::getModel('catalog/product')

->getResourceCollection()

->getAllIds();

// good way (better performance) @see Mage_Catalog_Model_Product_Action

$oProductActionModdel = Mage::getSingleton('catalog/product_action');

$oProductActionModdel->updateWebsites(

$aProductIds,

$aWebsiteIDs,

'add'

);

}

This was much more performant, than saving each product all the time. By the […]

Get all attribute options

9th June 201610th February 2018 SheldonNo Comments

To get all attribute options from a Magento dropdown attribute (select field) you can use the following snippet:

<?php
$oAttibute = Mage::getModel('eav/config')->getAttribute(Mage_Catalog_Model_Product::ENTITY, 'sheldon_special');
$aOptions = $oAttibute->getSource()->getAllOptions();
var_dump($aOptions);

<?php

$oAttibute = Mage::getModel('eav/config')->getAttribute(Mage_Catalog_Model_Product::ENTITY, 'sheldon_special');

$aOptions = $oAttibute->getSource()->getAllOptions();

var_dump($aOptions);

That gives you an array like that:

<?php
$aOptions = {array} [6]
 0 = {array} [2]
  label = ""
  value = ""
 1 = {array} [2]
  label = "best"
  value = "306"
 2 = {array} [2]
  label = "new"
  value = "305"
 3 = {array} [2]
  label = "no"
  value = "304"
 4 = {array} [2]
  label = "sale"
  value = "307"
 5 = {array} [2]
  label = "special"
  value = "632"

<?php

$aOptions = {array} [6]

0 = {array} [2]

label = ""

value = ""

1 = {array} [2]

label = "best"

value = "306"

2 = {array} [2]

label = "new"

value = "305"

3 = {array} [2]

label = "no"

value = "304"

4 = {array} [2]

label = "sale"

value = "307"

5 = {array} [2]

label = "special"

value = "632"

This can be used as source for a system config field for example. See my blogpost about Category dropdown element. To get a specific value by given label, you can […]

Load product attributes more performant

26th May 2016 SheldonNo Comments

Recently I had performance issues when importing several ten tausend products. The problem was, that I always used the “normal” product entity model to load attribute values. The following snippet shows, how to load product attributes directly instead. Therefore I use the product resource singleton.

<?php
$iProductId = $aChange['pid'];
$oItem = new Varien_Object;

/**
 * The old way: Baaaaaad and slow!!!
 **/
$oProduct = Mage::getModel('catalog/product')->load($iProductId); // loads all attributes and initializes model completely

# simple text attributes
$oItem->setName($oProduct->getName());
$oItem->getSku($oProduct->getSku());
$oItem->setSheldonArticlenbr($oProduct->getSheldonArticlenbr());
$oItem->setSheldonColor($oProduct->getSheldonColor());

# option value attributes (select boxes)
$oItem->setSheldonSize($oProduct->getAttributeText('sheldon_size'));

/**
 * The old way END
 **/

/**
 * The new way!!! Gooooood! Fast! Queries database directly and selects only necessary attributes
 **/
/* @var Mage_Catalog_Model_Resource_Product $rProduct */
$rProduct = Mage::getResourceSingleton('catalog/product');

# simple text attributes
$oItem->setName($rProduct->getAttributeRawValue($iProductId, 'name', Mage::app()->getStore()));
$oItem->getSku($rProduct->getAttributeRawValue($iProductId, 'sku', Mage::app()->getStore()));
$oItem->setSheldonArticlenbr($rProduct->getAttributeRawValue($iProductId, 'sheldon_articlenbr', Mage::app()->getStore()));
$oItem->setSheldonColor($rProduct->getAttributeRawValue($iProductId, 'sheldon_color', Mage::app()->getStore()));


# option value attributes (select boxes)
$iRawSize = $rProduct->getAttributeRawValue($iProductId, 'sns_size', Mage::app()->getStore());
$oItem->setSheldonSize($rProduct->getAttribute('sheldon_size')->getSource()->getOptionText($iRawSize));

<?php

$iProductId = $aChange['pid'];

$oItem = new Varien_Object;

/**

* The old way: Baaaaaad and slow!!!

**/

$oProduct = Mage::getModel('catalog/product')->load($iProductId); // loads all attributes and initializes model completely

# simple text attributes

$oItem->setName($oProduct->getName());

$oItem->getSku($oProduct->getSku());

$oItem->setSheldonArticlenbr($oProduct->getSheldonArticlenbr());

$oItem->setSheldonColor($oProduct->getSheldonColor());

# option value attributes (select boxes)

$oItem->setSheldonSize($oProduct->getAttributeText('sheldon_size'));

/**

* The old way END

**/

/**

* The new way!!! Gooooood! Fast! Queries database directly and selects only necessary attributes

**/

/* @var Mage_Catalog_Model_Resource_Product $rProduct */

$rProduct = Mage::getResourceSingleton('catalog/product');

# simple text attributes

$oItem->setName($rProduct->getAttributeRawValue($iProductId, 'name', Mage::app()->getStore()));

$oItem->getSku($rProduct->getAttributeRawValue($iProductId, 'sku', Mage::app()->getStore()));

$oItem->setSheldonArticlenbr($rProduct->getAttributeRawValue($iProductId, 'sheldon_articlenbr', Mage::app()->getStore()));

$oItem->setSheldonColor($rProduct->getAttributeRawValue($iProductId, 'sheldon_color', Mage::app()->getStore()));

# option value attributes (select boxes)

$iRawSize = $rProduct->getAttributeRawValue($iProductId, 'sns_size', Mage::app()->getStore());

$oItem->setSheldonSize($rProduct->getAttribute('sheldon_size')->getSource()->getOptionText($iRawSize));

Option value position (select value sort order)

20th May 2016 Sheldon1 Comment

This Magento shell script sorts the values of a given attribute after the order of values in a given CSV file (sets option value position).

Query Magento database object oriented

Naturally you can query Magento database directly as described in my earlier post about querying Magento database. But a much smarter way is it, to use exiting Magento objects and constructs like that:
